I voted that it varies. If it's on the weekend then it's the whole family. During the week usually just me and the two youngest. Sometimes if I don't make it or I need to go somewhere like Costco then it's my with all 3 after DS1 gets out of school. Past few months though with a new baby and DH was very sick and in the hospital I ordered online and had it delivered to the house. I'm actually about to do that this week although I ran into Whole Foods with just DD yesterday and picked up a few items.
